Web API or Application Programming Interface is a framework for building HTTP services that can be accessed in various platforms such as web browsers and mobile devices. API coders or developers can do a wide range of tasks—from manipulating documents and graphics to embedding content on your own media channel. API is a fundamental knowledge a web developer must learn, especially that the Internet is growing bigger and becoming more advanced as years go by. Moreover, businesses are investing on web-based services to optimize their business products. Hence, software engineering/management skills are highly-valued.
